Asterisk and monitoring are time sensitive applications. VM's are not
good canidates for these types of services. Go to the MRTG discussions
and you will get the same answer, stay away from VM. The time shift that
VM's introduce cause huge issues when mapping time sensitive data.

And Asterisk is time sensitive. A webserver or database server are not
time sensitive applications where time shifts of a few milliseconds are
not noticed. But with Asterisk if the time is shifting 20 or 30 ms
frequently, it will cause all sorts of issues.

Use VM's where and when useful. This scenerio is not a good candiate for
virtualization.
